Hi Debbie,

Just google Pub Med. Then type in CRPS and tDCS, or CRPS and Chronic pai or tDCS and safety. Some articles are printed in full. Others there is just an abstract. If you see one that looks particularly promising and it is only listed in abstract form you may write to the author to request a copy for your personal use. (If you obtain a copy this way you may not post the article).

You may also be able to obtain some articles from your local college, or if you have a connection to a large university or medical school your contact might obtain a copy for you.

One article will lead you to the next.

This is not a hard process, just demands a little persistence.

Hope this helps.
